A product-oriented teaching and training system has been developed for speech handicapped persons which helps to control of their speech production by a visual feedback. This method helps teachers to obtain better and quicker results. Furthermore, this interactive feedback system has a game like strategy, which gives the patients a new motivation to practice alone. Patients may simultaneously modify and correct their defective articulation by real-time interaction between speech sounds and computer displays. This new speech therapy method is built up in four different steps: (1) sound preparation, (2) sound development, (3) practice in words, (4) practice in sentences (automation). The method is mainly useful for patients who are hard of hearing or deaf, but serves for dyslalic cases too. With the help of a special preprocessor the system analyzes similarly to the way that man hears, and visualizes it in an illustrative and playful way. Patients can compare their pronunciation with correct one (etalon). The therapy program is built up for being used in several different cases of etiological background (such as hearing problems, claft palate, disorders of auditory perception, etc.), and for various languages. There is a set of modules in it for building dictionaries according to the language and/or the kind of the defective pronunciations. This paper presents both the general methodological steps and the results of the correction of sygmatism.
